SI5338F-B04216-GMR

Overview

The SI5338F-B04216-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. It operates within a core supply range of 1.71 V to 3.63 V and supports frequencies up to 710 MHz. The device features low phase jitter of 0.7 ps RMS typical, configurable output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL, and an I2C/SMBus interface for configuration.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with true zero ppm accuracy.
• Low phase jitter performance of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS standards.
• Highly-configurable output drivers supporting up to four differential outputs, eight single-ended outputs, or mixed configurations.
• Flexible input reference options including external crystals (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential inputs (5-710 MHz).

Applications

• Ethernet switch/router timing
• PCIe Gen1/2/3/4 clocking
• Processor and FPGA clock generation
• Broadcast video/audio timing systems
• Telecom line cards and MSAN/DSLAM/PON equipment

Procurement Notes

Verify the specific ordering suffix B04216 against the manufacturer's current documentation to confirm the exact frequency plan and output configuration. Ensure compatibility with the required I2C address and voltage levels before integration. Check for moisture sensitivity labeling if storage conditions exceed specified limits.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single package. Verify that the target output signal formats (LVPECL, LVDS, etc.) and voltage levels (1.5V, 1.8V, 2.5V, 3.3V) match the load requirements. Confirm that the input reference source aligns with the supported frequency ranges for crystal or direct drive inputs.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators and buffers, consolidating frequency synthesis into a 4x4 mm QFN-24 package. The device integrates a PLL, MultiSynth synthesizers, and configurable output drivers to reduce board space and power consumption in high-performance digital systems.

Replacement Considerations

Direct pin-to-pin replacements within the same family may require reprogramming via ClockBuilder Pro software to match the original frequency plan. Verify that alternative SKUs support the same output count and format combinations. Cross-referencing with older Si533x variants requires checking for differences in jitter performance and input/output electrical characteristics.
